In total, Sinner has won 36 of his last 37 matches, his only defeat coming against Carlos Alcaraz in the final of October’s China Open.

Keys, ranked 14th and seeded 19th, prevented Sabalenka from earning what would have been her third women's trophy in a row at the Australian Open — something last accomplished by Martina Hingis from 1997-99 — and her fourth major title overall.

The American tennis player, 29, secured her first grand slam title on Jan. 25, achieving a breakthrough win over world No. 1 Aryna Sabalenka, who was vying for what would have been a historic three-peat. The women's singles match at Melbourne's Rod Laver Arena saw Keys win 6-3, 2-6, 7-5.
